Major depressive disorder, single episode, unspecified: ICD-10 F32.9

ICD-10 F32.9 (Major depressive disorder, single episode, unspecified) falls in Medicare's Depression chronic-condition class. In 2024, 1,001,567 Medicare providers had Depression patients in their panels: an estimated 87.2M panel patients nationally, from public CMS data.

F32.9 maps to more than one condition class. Besides Depression, it also counts toward Mood Disorders. The provider ranking below uses the most specific class; the app applies all of them at once.

Where these numbers come from. Everything on this page is computed from CMS's public Medicare Physician & Other Practitioners - by Provider file for 2024, the most recent year released. CMS reports, for each provider, the share of their Medicare patient panel carrying each of 25 chronic-condition classes. "Est. patients" is panel size × that share, so a patient who sees three providers counts in three panels: these are panel-level estimates, not unique patient counts. Panel-prevalence estimate: these are providers whose patients carry this condition class, not providers who billed this exact code. Prevalence shares are top-coded at 75% and suppressed for small panels: a missing value never means zero. The data covers traditional Medicare fee-for-service only (no commercial insurance, no Medicare Advantage), and CMS suppresses low-volume lines before publishing. The code description is CMS's own ICD-10-CM wording. Comorbidity figures are ecological estimates from panel composition, not patient records. Prospect 811 organizes public data; it doesn't add to or alter it. Not affiliated with or endorsed by CMS. Full detail on the data page.
